Aston was a Knight of the Shire for the constituency of Staffordshire in the Parliament of March 1553 for 31 days—this was his only parliamentary experience.
He was knighted on 18 July 1560 by the 4th Duke of Norfolk for his service at the siege of Leith in that year.
He was commissioner of the (military) muster in 1586 (the year following the Spanish Armada).
[1] Aston's first marriage was in 1544 to Mary, daughter of Sir John Spencer of Althorp, Northamptonshire and Wormleighton Manor, Warwickshire;[1] and secondly, by 1551, to Elizabeth, daughter of James Leveson of Lilleshall, Shropshire.
